Bug ID: 51452
           Summary: oleaut32:varformat fails in Wine when the currency
                    sign has two characters or more
           Product: Wine
           Version: 6.10
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2

oleaut32:varformat fails in Wine when the currency sign has two characters or
more:

https://test.winehq.org/data/patterns.html#oleaut32:varformat

varformat.c:641: str=L"\062f.\0645.\200f 0.000"
varformat.c:643: Test failed: Unexpected hr 0x80020005.

In Morocco the currency sign has 5 characters. This is simply not supported by
VarParseNumFromStr().

But even the currency sign is only two characters VarParseNumFromStr() fails
because it advances a pointer by one character only. For instance with Polish:

varformat.c:641: str=L"0,000 z\0142"
varformat.c:643: Test failed: Unexpected hr 0x80020005.

Note that the w10pro64 TestBot Windows VMs have an incorrect UserDefaultLCID so
that these issues are not actually tested (see bug 51451). The w7u VMs are more
correct in this regard but only test simple European cases (€).
